Maxillary defects resulting from ablative oncologic surgery can be extensive and usually have complex contours. Impression procedures for such defects can be time consuming and cumbersome, challenging the skills of even the most‐experienced clinician. A well‐oriented impression tray with proper extension and adequate contour is essential for successfully capturing the relevant details in impression. This article describes a method using the patient's existing obturator prosthesis to simplify and expedite the fabrication of a lightweight individualized impression tray directly on an irreversible hydrocolloid impression, thus avoiding the preliminary impression procedure for the patient.
